Ecclesiastes 2:23
For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.
Ecclesiastes 5:18
Behold that which I have seen: it is good and comely for one to eat and to drink, and to enjoy the good of all his labour that he taketh under the sun all the days of his life, which God giveth him: for it is his portion.
